Description
その目的を達成するための本開示に係る車両用位置判定システムは、ユーザによって携帯される携帯端末から１ＧＨｚ以上の所定の周波数帯の電波を用いて送信される無線信号を受信することによって携帯端末の位置を推定する車両用位置判定システムであって、車両の車室内に設置された車室内アンテナを介して、携帯端末から送信される無線信号を受信する車室内受信部（１３２）と、車室内受信部が受信した無線信号の受信強度を車室内強度として検出する車室内強度検出部（１３３）と、車室外から到来する無線信号を受信するための車室外アンテナ（１２１）と、車室外アンテナを介して携帯端末から送信される無線信号を受信する車室外受信部（１２２）と、車室外受信部が受信した無線信号の受信強度を車室外強度として検出する車室外強度検出部（１２３）と、車室内強度検出部が検出した車室内強度及び車室外強度検出部が検出した車室外強度に基づいて、携帯端末が車室外に存在するか否かを判定する位置判定部（Ｆ５）と、を備え、車室外アンテナは、車両の外面部において、車両が備える窓部の近傍と見なすことができる所定領域に配置されていることを特徴とする。 The vehicle position determination system according to the present disclosure for achieving the object is a mobile terminal by receiving a wireless signal transmitted from a mobile terminal carried by a user using radio waves in a predetermined frequency band of 1 GHz or more. A vehicle interior receiver (132) that receives radio signals transmitted from a mobile terminal via an in-vehicle antenna installed in the vehicle interior, and a vehicle interior receiver (132), which is a vehicle position determination system that estimates the position of the vehicle. The vehicle interior strength detector (133) that detects the reception strength of the radio signal received by the indoor receiver as the vehicle interior strength, the vehicle interior antenna (121) for receiving the radio signal coming from outside the vehicle interior, and the vehicle interior exterior. An outdoor strength detector (122) that receives a wireless signal transmitted from a mobile terminal via an antenna, and an outdoor strength detector (123) that detects the reception strength of the wireless signal received by the outdoor receiver as the outdoor strength. ), And the position determination unit (F5) that determines whether or not the mobile terminal exists outside the vehicle interior based on the vehicle interior strength detected by the vehicle interior strength detection unit and the vehicle interior strength detected by the vehicle interior strength detection unit. The outdoor antenna is arranged in a predetermined region on the outer surface of the vehicle, which can be regarded as the vicinity of the window provided in the vehicle.
